Ivanka Trump and Jared Kushner Expecting First Child

Jared Kushner and Ivanka Trump attend the Costume Institute Gala Benefit to celebrate the opening of the &amp;quot;American Woman: Fashioning a National Identity&amp;quot; exhibition at The Metropolitan Museum of Art on May 3, 2010, in New York.

"I have been wanting to share some amazing news with you all for some time... I'm pregnant!" she wrote. "Jared and I couldn't be more excited."

Trump married Kushner, owner of the New York Observer, on Oct. 25, 2009, after she converted to Judaism.

She works for her father, real estate mogul and "The Apprentice" host Donald Trump, as the currently Executive Vice President of Development & Acquisitions at The Trump Organization. She also designs a jewelry line and is set to unveil a line of handbags and shoes in the spring.

The birth of her child will make Donald Trump a grandfather for the third time. Son Donald Trump Jr. and his wife Vanessa welcomed daughter Kai Madison in 2007 and son Donald John Trump III in 2009.
